EXAMPLES

A multi-center, placebo-controlled randomized, double-blind, 12-weekstudy with an open-label extension is performed to evaluate the efficacyand safety of AMR101 in patients with fasting triglyceride levels ≧500mg/dL. The primary objective of the study is to determine the efficacyof AMR101 2 g daily and 4 g daily, compared to placebo, in loweringfasting TG levels in patients with fasting TG levels ≧500 mg/dL and≦1500 mg/dL (≦5.65 mmol/L and ≦16.94 mmol/L).

The secondary objectives of this study are the following:

-   1. To determine the safety and tolerability of AMR101 2 g daily and    4 g daily;-   2. To determine the effect of AMR101 on lipid and apolipoprotein    profiles;-   3. To determine the effect of AMR101 on low-density lipoprotein    (LDL) particle number and size;-   4. To determine the effect of AMR101 on oxidized LDL;-   5. To determine the effect of AMR101 on fasting plasma glucose (FPG)    and hemoglobin A_(1c) (HbA_(1c));-   6. To determine the effect of AMR101 on insulin resistance;-   7. To determine the effect of AMR101 on high-sensitivity C-reactive    protein (hsCRP);-   8. To determine the effects of AMR101 2 g daily and 4 g daily on the    incorporation of fatty acids into red blood cell membranes and into    plasma phospholipids;-   9. To explore the relationship between baseline fasting TG levels    and the reduction in fasting TG levels; and-   10. To explore the relationship between an increase in red blood    cell membrane eicosapentaenoic acid (EPA) concentrations and the    reduction in fasting TG levels.

The population for this study is men and women (women of childbearingpotential will need to be on contraception or practice abstinence)>18years of age with a body mass index ≦45 kg/m² who are not onlipid-altering therapy or are currently on lipid-altering therapy.Patients currently on statin therapy (with or without ezetimibe) will beevaluated by the investigator as to whether this therapy can be safelydiscontinued at screening, or if it should be continued. If statintherapy (with or without ezetimibe) is to be continued, dose(s) must bestable for weeks prior to randomization. Patients taking non-statin,lipid-altering medications (niacin >200 mg/day, fibrates, fish oil,other products containing omega-3 fatty acids, or other herbal productsor dietary supplements with potential lipid-altering effects), eitheralone or in combination with statin therapy (with or without ezetimibe),must be able to safely discontinue non-statin, lipid-altering therapy atscreening.

Approximately 240 patients will be randomized at approximately 50centers in North America, South America, Central America, Europe, India,and South Africa. The study will be a 58- to 60-week, Phase 3,multi-center study consisting of 3 study periods: (1) A 6- to 8-weekscreening period that includes a diet and lifestyle stabilization andwashout period and a TG qualifying period; (2) A 12-week, double-blind,randomized, placebo-controlled treatment period; and (3) A 40-week,open-label, extension period.

During the screening period and double-blind treatment period, allvisits are to be within ±3 days of the scheduled time. During theopen-label extension period, all visits are to be within ±7 days of thescheduled time. The screening period includes a 4- or 6-week diet andlifestyle stabilization period and washout period followed by a 2-weekTG qualifying period. s) must be stable for weeks prior torandomization.

The screening visit (Visit 1) will occur for all patients at either 6weeks (for patients not on lipid-altering therapy at screening or forpatients who will not need to discontinue their current lipid-alteringtherapy) or 8 weeks (for patients who will require washout of theircurrent lipid-altering therapy at screening) before randomization, asfollows:

Patients who do not require a washout: The screening visit will occur atVisit 1 (Week −6). Eligible patients will enter a 4-week diet andlifestyle stabilization period. At the screening visit, all patientswill receive counseling regarding the importance of the NationalCholesterol Education Program (NCEP) Therapeutic Lifestyle Changes (TLC)diet and will receive instructions on how to follow this diet. Patientswho will require a washout: The screening visit will occur at Visit 1(Week −8). Eligible patients will begin a 6-week washout period at thescreening visit. Patients will receive counseling regarding the NCEP TLCdiet and will receive instructions on how to follow this diet. Sitepersonnel will contact patients who do not qualify for participationbased on screening laboratory test results to instruct them to resumetheir prior lipid-altering medications.

At the end of the 4-week diet and lifestyle stabilization period or the6-week diet and stabilization and washout period, eligible patients willenter the 2-week TG qualifying period and will have their fasting TGlevel measured at Visit 2 (Week −2) and Visit 3 (Week −1). Eligiblepatients must have an average fasting TG level ≧500 mg/dL and ≦1500mg/dL (≧5.65 mmol/L and ≦16.94 mmol/L) to enter the 12-week double-blindtreatment period. The TG level for qualification will be based on theaverage (arithmetic mean) of the Visit 2 (Week −2) and Visit 3 (Week −1)values. If a patient's average TG level from Visit 2 and Visit 3 fallsoutside the required range for entry into the study, an additionalsample for fasting TG measurement can be collected 1 week later at Visit3.1. If a third sample is collected at Visit 3.1, entry into the studywill be based on the average (arithmetic mean) of the values from Visit3 and Visit 3.1.

After confirmation of qualifying fasting TG values, eligible patientswill enter a 12-week, randomized, double-blind treatment period. AtVisit 4 (Week 0), patients will be randomly assigned to 1 of thefollowing treatment groups:

AMR101 2 g daily,

AMR101 4 g daily, or

Placebo.

During the double-blind treatment period, patients will return to thesite at Visit 5 (Week 4), Visit 6 (Week 11), and Visit 7 (Week 12) forefficacy and safety evaluations.

Patients who complete the 12-week double-blind treatment period will beeligible to enter a 40-week, open-label, extension period at Visit 7(Week 12). All patients will receive open-label AMR101 4 g daily. FromVisit 8 (Week 16) until the end of the study, changes to thelipid-altering regimen are permitted (e.g., initiating or raising thedose of statin or adding non-statin, lipid-altering medications to theregimen), as guided by standard practice and prescribing information.After Visit 8 (Week 16), patients will return to the site every 12 weeksuntil the last visit at Visit 11 (Week 52).

Eligible patients will be randomly assigned at Visit 4 (Week 0) toreceive orally AMR101 2 g daily, AMR101 4 g daily, or placebo for the12-week double-blind treatment period. AMR101 is provided in 1 gliquid-filled, oblong, gelatin capsules. The matching placebo capsule isfilled with light liquid paraffin and contains 0 g of AMR101. During thedouble-blind treatment period, patients will take 2 capsules (AMR101 ormatching placebo) in the morning and 2 in the evening for a total of 4capsules per day. Patients in the AMR101 2 g/day treatment group willreceive 1 AMR101 1 g capsule and 1 matching placebo capsule in themorning and in the evening. Patients in the AMR101 4 g/day treatmentgroup will receive 2 AMR101 1 g capsules in the morning and evening.

Patients in the placebo group will receive 2 matching placebo capsulesin the morning and evening. During the extension period, patients willreceive open-label AMR101 4 g daily. Patients will take 2 AMR101 1 gcapsules in the morning and 2 in the evening.

Safetyassessments will include adverse events, clinical laboratorymeasurements (chemistry, hematology, and urinalysis), 12-leadelectrocardiograms (ECGs), vital signs, and physical examinations

For TG, TC, HDL-C, calculated LDL-C, calculated non-HDL-C, and VLDL-C,baseline will be defined as the average of Visit 4 (Week 0) and thepreceding lipid qualifying visit (either Visit 3 [Week −1] or if itoccurs, Visit 3.1) measurements. Baseline for all other efficacyparameters will be the Visit 4 (Week 0) measurement.

For TC, HDL-C, calculated LDL-C, calculated non-HDL-C, and VLDL-C, Week12 endpoint will be defined as the average of Visit 6 (Week 11) andVisit 7 (Week 12) measurements. Week 12 endpoint for all other efficacyparameters will be the Visit 7 (Week 12) measurement.

The primary efficacy analysis will be performed using a 2-way analysisof covariance (ANCOVA) model with treatment as a factor and baseline TGvalue as a covariate. The least-squares mean, standard error, and2-tailed 95% confidence interval for each treatment group and for eachcomparison will be estimated. The same 2-way ANCOVA model will be usedfor the analysis of secondary efficacy variables.

The primary analysis will be repeated for the per-protocol population toconfirm the robustness of the results for the intent-to-treatpopulation.

The primary efficacy variable will be the percent change in fasting TGlevels from baseline to Week 12. A sample size of 69 completed patientsper treatment group will provide ≧90% power to detect a difference of30% between AMR101 and placebo in percent change from baseline infasting TG levels, assuming a standard deviation of 45% in TGmeasurements and a significance level of p<0.01. To accommodate a 15%drop-out rate from randomization to completion of the double-blindtreatment period, a total of 240 randomized patients is planned (80patients per treatment group).
